How is gun powder measured?
The only way to do this is by measuring the powder charge. When black powder was the only powder shooters used, it was most often measured by volume. Due to the burning characteristics of modern smokeless powders, it should be measured by weight. However, if done carefully, it can also be measured by volume.

Do you measure every powder charge?
At typical shooting distances, a properly functioning powder measure works fine. But for longer ranges many handloaders prefer to weigh every charge for best accuracy.
